A fuel cell module including a membrane electrode assembly (MEA), a pressing plate, an anode collector, an anode flow channel plate, a cathode collector, and a cathode flow channel plate is provided. The MEA has a protrusion, and the pressing plate presses an edge of a cathode of the MEA. The pressing plate has a first opening to expose the protrusion. The anode collector is disposed on an anode of the MEA. The anode flow channel plate is disposed on anode collector. The anode collector is disposed between the anode and the anode flow channel plate. The cathode flow channel plate faces the cathode collector disposed on the cathode and the pressing plate to form a flow channel between an inner surface of the cathode flow channel plate and the cathode collector. The cathode flow channel plate has a concave portion corresponding to the protrusion.
